Add default class bound to be annotated even when interface bounds are present

[dbrosoft]

In class C below, the specified bound on type variable T is an interface bound. In the JAIF format, to specify annotating the first interface bound of the (first) parameter, one uses bound 0&1. If, as in the JAIF below, one specifies bound 0&0, the default class bound java.lang.Object should be generated and annotated, but the insertion currently fails.

// source
public class C {
  public <T extends java.io.Serializable> void foo(T t) {
  }
}

// JAIF
package :
annotation @A: @java.lang.annotation.Target(value={TYPE_USE})
class C:
    method foo(Ljava/util/Serializable;)V:
        bound 0 & 0: @A

The expected result is as follows:

// goal
public class C {
  public <T extends java.lang.@A Object & java.io.Serializable> void foo(T t) {
  }
}

Tests BoundClassMultiple and BoundMethodMultiple have been corrected and disabled until there is a fix.
